Summary

  • Load Babylon's glTF 2.0 serializer index only when GltfOutputBlock exports a GLB, so all glTF exporter extensions register together.
  • Export WebP and AVIF images through EXT_texture_webp and EXT_texture_avif, including required extension metadata and extension-owned image references.
  • Preserve core PNG and JPEG texture.source output, texture transforms, BasisU textures, Draco compression, and combined compression.

Testing

  • pnpm lint
  • pnpm test
  • pnpm build
